COMBINED THREADER, REAMER, AND WRENCH.

Application filed April 20, 1915.

To all whom it may concern:

Be it known that we, JACOB L. BROSCHART and EDWARD F. BERNEKING, citizens of the United States, residing at 1103 Harris avenue, Trenton, in the county of Grundy and State of Missouri, and Atchison, in the county of Atchison and State of Kansas, respectively, have invented a new and useful Combined Threader, Reamer, and Wrench; and we do hereby declare the following to be afull, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to an improved combined threader, reamer and wrench, in other words an object of the invention is to provide an improved stock for holding and operating either an internal or external threading die or a reamer, or an external threading die and reamer combined, or a wrench die.

Another object of the invention is to provide a simple, inexpensive, eflicient and practical device of this nature, having improved features of construction, and also provides a device of this nature, which may be used or employed in a limited space.

Another object ofthe invention is the pro- Vision of means whereby the device may be used for cutting quite a long thread on a pipe.

In practical fields the details of construction may necessitate alterations, falling within the scope of what is claimed.

The invention comprises N further features and combination of parts, as hereinafter set forth, shown in the drawings and claimed.

In the drawings :F igure 1 is a viewin perspective of the improved stock. Fig. 2 is a perspective view showing the other face of the stock. Fig. 3 is a longitudinal sectional view showing a die and a reamer held in the stock for reaming and cutting threads at the same time. Fig. 4c is an end view of a handle of the stock showing the groove in the end thereof for receiving the rib of the cap of the stem of the pawl. Fig. 5 is a face view of the cap or head of the stem of the ratchet. Fig. 6 is a sectional view on line 6-6 of Fig. 3, showing the reamer and the external'pipe threading means. Fig. 7 is a plan view of the stock showing an internal pipe tap or threading means. Fig. 8 is a sectional view on line 8 8 of Fig. 7.

Fig. is a sectional view through the stock showlng external threading means, whereby a long thread may be supplied on a pipe. Fig. 10 is a detail perspective View of the reamer. Fig. 11 is a View showing the stock holding a wrench die, for backing off or unscrewing a nut, and the opening in this die may be either square or other polygonal shape.

Referring more especially to the drawings, l designates the stock, which comprises an annular band 2 having a hollow shank 8, in which the tubular stock handle 4c is threaded as shown at 5. One edge portion of this annular band is provided with an inturned annular flange 6, whereas the inner circumference of the band adjacent the other edge portion of the band is provided with internal'threads 7 In all the figures excepting Fig. 9 an annular back plate 8 is provided, the edge portion of which is provided with a rabbet 9 to receive the inturned flange 6, and adjacent this back plate any form of die 10 may be arranged, either a die having thread cutters as shown at 11 in Figs. 2, 3, 6 and 9, or either a die as shown at 10 in Fig. 7 having a square opening 10 for backing oif nuts. This opening 10 may be any other shape than that shown. Threaded at 12in the back plate is a screw 13 having a conical head 14; to engage a suitable abutment merely indicated at 15 for pivotally supporting the stock while the same is being used to perform its work. This screw is supplied with a reduced portion 16, on which a suitable reamer or the like 17 is arranged. This reamer is employedfor reaming, cutting or removing the bur upon the inner circumference of a pipe or the like. This reaming or removing of the bur may be accomplished independently, or at the same time with the cutting of the thread on the exterior of the pipe. The end face. of the reamer 17 is constructed with a rib 18, which engages a correspondingly shaped recess or groove 19 upon the inner face of the back plate, so that the reamer and the back plate will rotate as one body. Regardless of the form of guide to be used, it is to be understood, however, that each die is to be constructed with an aperture 20, whereas the back plate is designed to have an aperture 21, to receive a thumb pin 22, which in turn enters the aperture 20, in order to connect the die to the back plate.

The die is connected to the back or die plate, only when it is desired to ream or remove the bur, and cutting'exterior threads at the same time, and also when desiring to out the interior and external threads 011 a pipe at the same time, as disclosed clearly in Figs.

7 and 8. When it is desired to ream the" inner surface of the pipe without cutting external threads, the thumb pin 22 remams 1n sald registering apertures, so that the back plate and thedie will rotate together, but in vided with the usual cutting edges 23,

whereas inv Figs. 7 and 8 an internal thread cutting die 24 having thread cutters 25 is arranged or applied to the reduced portion 16 of the screw 13, and in which case this die s provided with a rib 26 similar to the rib 18 to be received in the groove 19 of the back or die plate, so that the guide 24 will rotate with the back plate, and to cut internal threads the thumb pin remains in the apertures 20 and 21. However, in this case when it is desired to cut internal threads without cutting external threads the opening of the die 10 is circular. As shown in Fig. 9 a pipe may be provided witha thread of considerable length. In this instance the back plate may be removed, and the die 10 allowed to engage the inturned flange 6 of the band 2 of the stock, or instead of the back plate 8 a ring 28 havinga rabbet 29 to engage the flange 6 may be employed,

thereby permitting the die 10 as shown 1n Fig.9 to rotate against the ring. In this manner it willbe observed that a pipe, when it is to be supplied with external threads of considerable length, may extend entirely through the die and .the band as shown in Fig. 9. Every formof die 10, whether used for backing off nuts or cutting external threads are designed to have teeth preferably of the type shown at 30, and mounted in the hollow shank 3 is a ratchet dog 31 having a stem 32 threaded to the dog as shown at 33. Interposed between the dog and a collar 34 on the stem adjacent one end of the handle 4, is a coil spring 35, the action of which holds the nose 36 of the ratchet dog in engagement with the teeth 30 of the die member 10, and in such wise, that when the stock handle 4 is thrown in one direction, the die will rotate with the stock band,*so that the cutters 11 or the reamer willperform their work, and when the handle 4 is moved in the opposite direction, the

nose'36 is so beveled as shown at 37 as to slip over the teeth. In this manner an intermittent motion is imparted to the die and the reamer. Threaded upon the stock handle as at 38 is a sleeve 39, the end portion of which is provided with a transverse groove 40. Threaded or otherwise secured upon the stem 32 as shown at 41 is a cap 42 having a reduced portion 43 telescoping into one end of the sleeve 39. Formed upon one face of the cap 42 upon opposite sides of the reduced portion 43 are lugs 44, which enter the grooves 40 of the sleeve 39, to prevent annular displacement of the ratchet dog 31, when the same is in action. By grasping the cap 42 and pulling outwardly thereon the nose of the ratchet dog may be disengaged from the teeth 30 of the die, so that the stock handle 4 may be moved to another position more conveniently, when such is necessary. Referring to Fig. 3 it is to be noted that the ratchet dog may be reversed in position to that shown, by pulling outwardly upon the cap, and imparting a half revolution to the same, and allowing the lug 44 to engage the groove 40, subsequently to permitting the spring 35 to restore the nose 36 of the dog in engagement with the teeth 30 of the die, in order that an intermittent motion may be imparted to the die in the direction opposite to that previously set forth. To hold the die 10 or similar member in the band a ring 50 is connected to the threads 7 of the band, and this ring isprovided with openings 51 to receive a spanner-wrench, whereby the ring may be screwed in place.

The invention having been set forth, what is claimed as new and useful is 1. A stock and die comprising a band having a stock handle, aback plate loosely movable in said band and provided with a concentrically arranged cutter, an annular die carried by the back plate loosely movable in saidband and having outer circumferential teeth, and means in said handle to cooperate with the teeth for imparting intermittent motion to the die.
